The vending machine sanitizes the container before any fluid is dispensed into the container. Further, the machine provides the branding of the container depending on the consumer selection allowing people and consumer recognition of the product and enticing manufacturers to participate.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention is related to a method and apparatus for refilling a container but more specifically to the identification, user interaction, and sanitizing of a container and refilling of fluid having short shelf life fluids.
2. Discussion of the Background
Lately people are concerned about the environment and are looking for ways to protect it. For example, in order to reduce the use of plastic waste, reusable containers are now utilized. U.S. Pat. No. 4,929,818 to Bradburry, discloses a method of vending a containerized product using multiple fillings of the same container. The method includes the steps of placing machine-readable indicia or means for reading on the container indicative of the price charged for both the container and the product contained therein, and at the time of placement of said indicia, or subsequently to such placement, including at a location adjacent to said indicia, a stimulus-responsive machine-readable indicator capable of responding to a stimulus to undergo a change of state which is readable, conjunctively with said indicia, by a machine, to indicate a price to be charged solely for the product in the refilled container. After initial vending of the container and the product, the container is refilled with product at least once, while concurrently, during each such refilling, stimulating said indicator to cause it to undergo said change, whereby the customer buying a refill of product is charged, on the basis of the subsequent machine reading, only for such product as is placed in the container during the refilling thereof. The container can be used for refilling multiple times, however the container is limited to only be filled with the same fluid or long lasting products. No cleaning or sanitation of the container is done in order to provide for fluids of short expiration time such as milk, juice and others.
Another example of environmental awareness is U.S. Pat. No. 6,578,763 to Brown, which discloses a method and apparatus for vending a containerized liquid product to a vendee, after an original liquid container has been emptied, by successive refilling of the product and utilizing machine-readable indicia on the container, a discount ticket or coupon being dispensed to the vendee upon completion of the filling of the container. The same principles of Bradburry apply here with the only difference that a vending machine will provide a discount ticket upon the completion of the container. Again the product is limited to the use of long lasting fluid, since no sanitation process is disclosed.
Therefore there is a need to provide a method and apparatus such as a vending machine for fluid refilling of fluid having a short shelf life. The present invention provides a vending machine that sanitizes the container as part of the refilling process in order to reduce and avoid the contamination of the refilled product.
SUMMARY OF THE INVENTION
The present invention provides a method and apparatus for refilling a reusable container in order to reduce the non-biodegradable waste and environment contamination.

BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying drawings which are incorporated herein constitute part of the specifications and illustrate the preferred embodiment of the invention.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The present invention overcomes all the disadvantages mentioned above by providing a method and apparatus for refilling a container with fluids having a short shelf life.
The main components of the preferred embodiment are a container 1 and a vending machine 3.
The container 1 is configured to interact with the vending machine 3 in such way that a smoother cleaning and refilling process is provided.
As shown in
As mentioned before, the container 1′ is provided with lateral grooves 1d and bottom grooves 1c used as engaging means for the vending machine in order to rotate or manage the movement of the container during the process.
The vending machine 3, as show in
- Container is positioned and engaged inside the vending machine's chamber.
- Access and Acquire user information through the readable means and/or data base.
- Container label is removed
- Verify damages in the container
- Exchange of information with user
- Clean container
- Refill Container
- Seal container
- Edit and Store information regarding user, product and others.
The chamber 4, as shown in
As mentioned above, first the container is positioned inside the chamber at section A in such way that protrusions 3e engage bottom grooves 1c and lock the container in position while controlling the rotation of the container 1. The vending machine opening 3d is closed and the start button is pressed in order to begin the cleaning and refilling process. At this point the container cap has been removed manually.
The information at the readable means 1′, 1″ is accessed by means of a reader such as a RFID reader 5, as shown in
The customer exchanges information with the database using the information access mechanism 3b in such way that the container is customized to identify the person/consumer and provide a quick menu for this customer based on the customer preferences. Also since the container 1 needs to be customized the user may then have to confirm or submit a PIN (personal identification number) or password which is related to the container for future refilling. In order to have customer information available for future refilling or any other uses or features, when the container is customized for the first time, information is requested from the user in order to provide the database with usable data such as payment method and preferences, including a submission of a PIN or password. Every time the container 1 is inserted in the machine's chamber 4 the machine will ask for the identity by personal identification number (“PIN”) or some other means. In other words, a user profile can be created, which resides in the database located outside the machine 3 and is pulled up by placing the container in the machine, and can be used or altered after placing the PIN or password.
It has to be understood that removing the label is necessary since the label needs to be updated in order to provide visible information for the customer such as the expiration date of the new fluid usually marked at the new label. The label can be removed and attached manually to the container 1, for example, using labels made of PVC Film or any other material which sticks to the container surfaces without any adhesive and removed without leaving behind any residue. The new label provided by the vending machine 3 after the payment and selection of the fluid is performed will display information such as but not limit to the brand, expiration date and nutrition facts. Another option is a vending machine 3 with a label detaching process which after the fluid selection and payment is performed removes the old label from the container's outer surface as shown in
After the cutting is performed the container is rotated clockwise until the area pierced by the razor 7a reaches the label remover 8. Subsequently, the label remover 8 starts removing the label, for example, by suction while the container rotates in a counterclockwise direction. Next the label remover pulls back and the label detaching process is completed.
Before the container is refilled and to avoid the new fluid being spilled a container's damage inspection is performed. A light emitter 10a is inserted through the container opening 1b and a receiver 10b is positioned outside in order to receive the signal from the emitter and discern if the container is damaged. The receiver 10b may be static while the container rotates or the receiver may rotate while the container is static. As mentioned before the rotational motion of the container is controlled by protrusion 3e. If the container 1 is damaged the vending machine will finalize the process and an alert the customer. It has to be understood that in case the customer let the container with the cap on, the light emitter will remain outside the container and therefore the receiver 10b will recognize the container as damage.
After the damage inspection is completed the container moves to the B stage wherein the cleaning process begins. In the instant case the cleaning process is performed by turning the container upside down.
The container moves to the next and final stage C wherein the container is labeled and refilled with the new fluid.
